Osteossarcoma canino: casos clínicos

Abstract

A doença oncológica tem suscitado uma crescente preocupação em Medicina Veterinária. O osteossarcoma é a neoplasia primária mais comum no osso e afeta principalmente cães geriátricos de raças grandes/gigantes. Na maioria dos casos, o tumor primário localiza-se no esqueleto apendicular, no entanto também se pode localizar no esqueleto axial e até, embora mais raro, ter uma localização extra-esquelética. A sua etiologia não é totalmente conhecida, podendo resultar de fatores genéticos, moleculares e/ou físicos. Os sinais clínicos são variáveis, de acordo com o tipo anatómico de osteossarcoma. O diagnóstico deve conjugar métodos imagiológicos e histopatológicos. Sendo o osteossarcoma um tumor muito agressivo e com elevada taxa de metastização, a imagiologia tem, também, um importante papel na identificação da doença metastática. As opções terapêuticas devem incluir controlo do tumor primário com cirurgia e/ou radioterapia associado a quimioterapia adjuvante. Por vezes, há casos em que apenas é implementado tratamento paliativo. Este trabalho tem como objetivo fazer uma revisão atualizada sobre o osteossarcoma e expor e discutir casos clínicos.
